Example(s)
The following example sets up partition #1:
CLI> set rec-buffer -partition 1 -buffer-type receive -remote-boxid
"00DXL#########ET06F21AUABCPJ000002######" -buffer-size 128mb -forwarding-interval 1 -halt-wait-timer 15 -
monitoring-time 5
The following example changes the defined size of partition #2 to 256MB:
CLI> set rec-buffer -partition 2 -buffer-size 256mb
Optional. Specifying "enable" for this parameter may improve the Write I/O response during
initial copying of an REC Consistency mode copy session. If heavy-load Write I/O continues, an
extended period of time may be required to achieve an equivalent state. To prevent this from
occurring, make sure that the Write I/O during an initial copy is well below the REC line
throughput.
enable The I/O response priority mode is enabled.
disable The I/O response priority mode is disabled.
Optional. Specifying "enable" for this parameter may improve the Write I/O response while an
REC Consistency mode copy session maintains an equivalent state. If the Write I/O response is
affected even slightly, the REC buffer is changed to HALT status and the copy order may not be
guaranteed for an extended period of time. This parameter is effective only when the HALT
wait timer is set to 0 seconds.
enable The Immediate Halt mode is enabled.
disable The Immediate Halt mode is disabled.
